Baltimore Ravens' Brawl In Washington, D.C. -- Jacoby Jones Injured

Baltimore Ravens wide receiver Jacoby Jones was hurt early this morning after a brawl erupted on a party bus filled with his Ravens teammates ... TMZ has learned.

It happened after a night of partying in Washington D.C. celebrating Bryant McKinnie's birthday.

Sources at the scene tell us ... at about 3 AM, as people were leaving Opera Ultra Lounge, people on the bus began fighting. In addition to teammates, we're told at least one stripper was on board.

One eyewitness tells us he saw a bottle being swung at Jacoby Jones -- it connected with his head and hurt him. We're told an ambulance was called "for a bleeding male" but he was not taken to the hospital.

Our sources say a stripper named Sweet Pea is the one who hit Jacoby with a gigantic Ace of Spades bottle and this may have triggered the brawl. We're told the bottle smashed over his head and he was "bleeding everywhere."

We're told Jacoby's friends tried to retaliate against Sweet Pea but Bryant McKinnie tried to stop him, and a fight broke out between the friend and Bryant.

FYI ... Jacoby is currently injured and hasn't played since week 1.

Police responded to the scene but no arrests were made. We're told there was evidence of an assault but no one cooperated with cops.
